Create an empty map

Function: Create an empty map​

This function allows you to generate a new, blank collection of information, often referred to as a "map" or "dictionary." Think of it as creating an empty folder or an empty spreadsheet where you can later add various pieces of data, each identified by a unique label. This is useful when you need to start building a collection of related data from scratch within your application.

Real-Life Examples,

Here are some practical ways you can use the "Create an empty map" function:

  1. Initializing Customer Preferences:

    • Inputs: None

  2. Preparing a Shopping Cart for a New Order:

    • Inputs: None
    • Result: An empty map named currentShoppingCart is created. As a customer adds items, you can populate this map with product IDs as keys and quantities as values (e.g., product123: 2, product456: 1).

  3. Collecting Form Submission Data:

    • Inputs: None
    • Result: An empty map named formData is created. When a user fills out a form, you can store each field's name and its entered value into this map (e.g., firstName: "John", email: "[email protected]").
